It is a new razor, from what I understand the head is largely the same style/design but it's got a bigger blade gap. It's supposed to be more aggressive than the normal Masamune. It also has a new handle design which personally I don't like at all:

I went ahead and ordered the normal Masamune last week as I prefer smaller blade gaps and the new handle is just weird looking to me.

Second shave (7 in the morning, with Perma Sharp): well, the second time it went even better. The shave was smooth and smooth, and in complete safety (thanks also to Perma-Sharp), and in the end I was equally smooth, and now it's almost 7 pm and I still feel as smooth as my feather (but without pins of blood).
The next blades will be Kai and Polsilver
The razor runs well, and for now it beats it on par with the Timeless SS 0.95 open comb. Compared to the Timeless I like the different weight distribution (sometimes I find the T. a bit heavy). Certainly the polished steel of the T. completed by a scalloped cork are of a unique beauty (for me). But I like that too, even if it's less scenic. What we lose is the Blackbird O.C., which is less smooth and a little rough (without being more effective) with respect to both the Nodachi and the T.
